ʻO nā mea hoʻohana a pau o DLS a me nā mea likeʻole a me nā mea kiko'ī
DSL (Digital Subscriber Line) ke'enele pūnaewele wikiwiki nui no nā hale a me nāʻoihana e hakakā ana ma nā wahi he nui o ka'āina me nā kele pūnaewele a me nāʻano likeʻole. Hoʻolahaʻo DSL i kahi pūnaewele broadband me kahi laina phone phone. ʻO ka hapa nui o ka lawelawe DSL he mea like. Hiki ke hoʻokaʻawaleʻia nāʻano likeʻole o ka pūnaewele pūnaewele DSL ma keʻano likeymmetric a mea kaulike paha. ʻO kaʻoihana iʻoi aku ke kūpono iāʻoe ma muli o ka nui o ka holoʻana o ka holoʻana a iʻole e koi i ke kākoʻo no ka leo like a me nā leka uila.
Hana DSL
ʻO nāʻano maʻamau o DSL ka hoʻolakoʻana i kahi bandwidth pūnaewele no ka hoʻoukaʻana mai ka mea lawelawe pūnaewele i ka papahana o ka mea kākau ma mua o ka hoʻoukaʻana i kekahiʻaoʻao. Ma ka hoʻohaʻahaʻaʻana i ka nui o ka bandwidth i loaʻa i ka upstream, hiki i nā lawelawe ke hāʻawi aku i kahi pākuʻi hou aku i lalo, e hōʻike ana i nā makemake o ka mea kākau inoa.
ʻO kaʻenehana DSL maʻamau ka hale noho kūlana kūlana kūlana kaulana i kahi e hoʻohana nui ai nā mea hoʻohana pūnaewele home i ka bandwidth bandwidth.
Nāʻano maʻamau o DSL maʻamau e hoʻokomo i kēia mau mea:
- Hoʻolahaʻo ADSL (Asymmetrical Digital Subscriber Line) i ka piʻiʻana o ke alapiʻi a hiki i 8 Mbps a me ka piʻiʻana o 384 Kbps. Kākoʻoʻo ia i ka lawelawe kelepona a me ka lawe pūnaewele i ka manawa like.
- ʻO ADSL 2+ he palapala hou o ADSL nāna e hoʻopuka i nā piʻi o ka piʻi a hiki i 20 Mbps a hoʻouka i nā wiki o ka piʻiʻana a hiki i 850 Kbps.
- ʻO ADSL Lite aʻo G.Lite kekahi palapala o ADSL nāna e hāʻawi i nā wikiwiki o ka piʻiʻana a hiki i ka 1 Mbps Downstream a me 512 Kbps hiki i ka wikiwiki.
- R-ADSL ('Ālia Laula Hoʻopihapala Kahua) hoʻopuka i nā kahe likeʻole e like me ADSL, akā, hiki ke hoʻololiʻia ka speed transmission e ke modem.
- ʻO ka VDSL ( Kelepona Kupaianaha Nui Loa Loa) heʻoi aku ka DSLʻoi aku. Hoʻolimalimaʻia nā piʻipili he nui a hiki i 52 Mbps a hiki i ka 2,3 Mbps ma luna o kahi kānana keleawe.
Nānā DSL
Hōʻike nāʻano likeʻole o nā loulou DSL i ka bandwidth likeʻole no nā loka a me nā hoʻoili. ʻO kaʻenehana DSL maʻamau ka meaʻoihana no nāʻoihana DSLʻoihanaʻoihana iʻoi aku ka nui o nā pono no ka hoʻoiliʻana i nāʻikepili. ʻO ia hoʻi kaʻenehana o ka kohoʻana no ka leo like a me nā leka uila,ʻo ia ka mea e makemake ai i ka wikiwiki nui ma nāʻaoʻaoʻelua no nā'ahamele kūpono.
Nā Lāhui o DSL hōʻailona:
- ʻO ke SDSL (Line Subscriber Line Symmetric) e hāʻawi i nā piʻi o ke kikowaena i uka a me lalo o ka piʻiʻana a hiki i 1.54 Mbps.
- Kānaehana likeʻoleʻo SHDSL (Line Line Subscriber Line) e like me SDSL, akā ua'āponoʻia nā papahanaʻelua. Ua'āponoʻiaʻo SHDSL e ka Hui'Āhui Hui PūʻIa, a uaʻaeʻiaʻo SDSL e ka European Standards Institute.
- Ua hoʻolālāʻia ka HSDL (Line Line Subscriber Line Subscriber) i nā makahiki mua o ka makahiki 1990, e lilo ana ia i hoʻokahi o nā hōʻailona kahiko o DSL. Ua hāʻawiʻo HDSL i nāʻikepili i hōʻea i 2.048 Mbps akā ua koiʻia nā laina kuhi he nui, a lilo iʻeleʻele.
Nā Kūlana'ē aʻe o DSL
ʻO ka IDSL (ISDN Digital Subscriber Line) heʻenehana DSL / ISDN pūnaewele. Ua hanaʻia me nāʻano DSL'ē aʻe akāʻaʻole i hoʻohana nuiʻia i kēia mau lā ma muli o nā wiki liʻiliʻi (144 Kbps maximum data rate) e kākoʻo. Loaʻa ka IDSL i nā manawa a pau ma ka pilina, me ka ISDN.
